Daryl,

Did you mean Flattening the Right Wrist?

No. I mean that there is a Left Wrist Paddlewheel Motion and a Right Forearm Paddlewheel Motion.

. And an equivalent could be “Clubface Paddlewheel Action” executed as a Left Wrist Paddlewheel Motion. Thus, though some procedures may cause the Clubface to “Close” in relation to the Plane Line, none will be an actual “Roll” of the Hands. See 2-C and 6-B-3-0. There is, however, the “Release Roll” (Swivel) which is a true rotation of the Hands into Impact alignments by Accumulator #3 with (10-18-A only). ................ That is the Geometry of Hinging.

It's what HK "means" by "True Rotation". He doesn't mean that the Hands "Roll" about themselves, but rather, they "Rotate" around the Hinge.

Photos 6-B-3-0 shows the Left Forearm version – using a slow back-and-forth motion with Horizontal Hinge Action. For the Right Forearm version, do likewise, applying Angled Hinge Action. Do both alternately until you see the distinct differences in the Rhythm and Clubhead Travel of all three of the Roll procedures.

I need to submit a video. Until then, don't pay any attention to me.
